Description
본 발명은 도로나 교면등에 포장체를 시공하는데 사용되는 포장재 조성물 및 그의 시공방법에 관한 것으로서, 보다 구체적으로는 지속적으로 가해지는 진동과 하중에 대한 내구성이 우수한 포장체를 제조할 수 있고, 가사시간이 길어서 면적이 넓은 도로나 교면등에 시공하기에 적합한 포장재 조성물 및 그의 시공방법에 관한 것이다.The present invention relates to a pavement composition used to construct a pavement on a road or a bridge, and a construction method thereof, and more particularly, it is possible to manufacture a pavement having excellent durability against continuously applied vibration and load, and the pot life It relates to a paving material composition suitable for construction on a long and wide road or bridge, and a construction method thereof.
폐로니켈슬러그를 재활용하여 포장재 조성물을 제조하는 종래기술로는 대한민국 등록특허 제10-1877790호 등에 게재된 바와 같이 메틸메타크릴레이트를 주성분으로 하는 폴리아크릴계 바인더 조성물과 폐로니켈슬러그를 혼합하여 포장재 조성물을 제조하는 방법을 게재하고 있으나, 상기 방법에서 사용하는 아크릴계 바인더 조성물은 우수한 강도를 구현하지만 신율이 낮아 포장체 제조시 포장체에 지속적으로 가해지는 진동과 하중에 의해 포장체가 쉽게 파손되어 내구성이 저하되는 문제가 있었고, 또한 아크릴계 바인더 조성물은 경화반응이 너무 빨라서 포장면적이 넓은 도로나 교면 등에 상기 아크릴계 바인더 조성물을 포설하기 어려운 문제가 있었다.As a prior art for manufacturing a packaging composition by recycling the spent nickel slug, as disclosed in Korean Patent Registration No. 10-1877790, etc., a polyacrylic binder composition containing methyl methacrylate as a main component and a waste nickel slug are mixed to prepare a packaging composition. Although the manufacturing method is disclosed, the acrylic binder composition used in the above method realizes excellent strength, but has a low elongation, so that the packaging body is easily damaged by vibrations and loads continuously applied to the packaging body during the manufacturing of the package, resulting in reduced durability. There was a problem, and the acrylic binder composition had a problem in that it was difficult to install the acrylic binder composition on a road or bridge with a large pavement area because the curing reaction was too fast.
또 다른 종래방법으로는 폴리아크릴계 바인더에 폴리우레탄 수지를 첨가하여 바인더 조성물을 제조한 후 이를 폐로니켈슬러그와 혼합하여 포장재 조성물을 제조하는 방법도 알려져 있으나, 상기 종래방법은 폴리아크릴계 바인더와 폴리우레탄 수지간의 상용성이 떨어져 이들을 균일하게 혼합하기 어려운 문제가 있었다.Another conventional method is a method of preparing a binder composition by adding a polyurethane resin to a polyacrylic binder and then mixing it with a closed nickel slug to prepare a packaging composition, but the conventional method is a polyacrylic binder and a polyurethane resin. There was a problem in that it was difficult to uniformly mix them due to poor compatibility between them.
또 다른 종래방법으로는 폴리우레탄 수지를 주성분으로 하는 폴리우레탄계 바인더 조성물과 폐로니켈슬러그를 혼합하여 포장재 조성물을 제조하는 방법도 실시되어 왔으나, 상기 방법에서 사용되는 폴리우레탄 수지는 신율이 뛰어나 진동 및 하중에 의해 포장체가 파손되는 것을 효과적으로 방지해 내구성은 우수하지만, 온도 변화에 의한 수축율이 너무 심하게 달라서 시공대상 도로 표면과의 접착강도가 떨어지는 문제가 있었다.As another conventional method, a method for preparing a packaging material composition by mixing a polyurethane-based binder composition containing a polyurethane resin as a main component and a closed nickel slug has been carried out. It effectively prevents the pavement from being damaged and has excellent durability, but the shrinkage rate due to temperature change was so different that the adhesive strength with the road surface to be constructed was poor.
상기 문제점을 해소하기 위하여 폴리우레탄수지의 주쇄내에 실리콘기를 도입하면서 폴리우레탄 바인더 조성물 내에 계면 접착력을 향상시키는 커플링제를 첨가시키는 방법도 알려져 있으나, 상기 종래방법 역시도 온도 변화에 따른 폴리우레탄수지의 수축율 변동을 효과적으로 제어할 수 없어서 접착강도가 떨어지는 문제가 있었다.In order to solve the above problem, a method of adding a coupling agent to improve interfacial adhesion in the polyurethane binder composition while introducing a silicone group into the main chain of the polyurethane resin is also known, but the conventional method also changes the shrinkage rate of the polyurethane resin according to the temperature change It was not possible to effectively control the adhesive strength, so there was a problem in that the adhesive strength was lowered.
본 발명의 과제는 폴리우레탄수지를 주성분으로 하는 바인더 조성물을 포함하여 신율이 뛰어나 진동 및 하중에 대한 내구성이 우수함과 동시에 온도 변화에 따른 수축율 변화가 최소화되어 시공대상 도로면과의 접착강도도 양호하고, 가사시간이 길어 포설할 면적이 넓은 장소에 시공이 용이한 포장재 조성물을 제공하는 것이다.The object of the present invention is to include a binder composition containing a polyurethane resin as a main component, which has excellent elongation, excellent durability against vibration and load, and at the same time minimizes the change in shrinkage due to temperature change, so that the adhesive strength with the road surface to be constructed is good. , to provide a packaging material composition that is easy to construct in a place with a large area to be installed due to a long pot life.
본 발명의 또 다른 과제는 상기 포장재 조성물을 이용하여 포장체를 시공하는 방법을 제공하는 것이다.Another object of the present invention is to provide a method for constructing a package using the packaging material composition.
이와 같은 과제를 달성하기 위해서, 본 발명에서는 폐로니켈슬러그 등의 골재 100중량부에 대하여 폴리우레탄 주쇄에 아크릴기가 도입된 폴리우레탄 바인더 조성물 10~15중량부와 표면에 폴리우레탄 수지가 코팅되어 있으며 길이가 10~15㎜인 폴리우레탄 수지 코팅 나일론 중공사(10) 3~6중량부를 혼합하여 포장재 조성물을 제조한다.In order to achieve the above object, in the present invention, 10 to 15 parts by weight of a polyurethane binder composition in which an acrylic group is introduced into the polyurethane main chain with respect to 100 parts by weight of aggregate, such as a closed nickel slug, and a polyurethane resin is coated on the surface and the length A packaging composition is prepared by mixing 3 to 6 parts by weight of a polyurethane resin-coated nylon
또한, 본 발명에서는 시공대상 도로(A) 표면에 프라이머층(B)을 형성시킨 후 그 위에 상기 포장재 조성물을 도포하여 포장재층(C)을 형성시켜준다.In addition, in the present invention, after the primer layer (B) is formed on the surface of the construction target road (A), the packaging material composition is applied thereon to form the packaging material layer (C).
본 발명의 포장재 조성물은 가사시간이 길어서 큰 도로와 같이 시공대상 면적이 넓은 공사를 하기에 적합하고, 포설한 포장재를 가열하는 방법으로 포장재의 경화시간을 조절할 수도 있다. 또한 폴리우레탄 바인더 조성물은 강도와 함께 신율도 우수하여 지속적으로 가해지는 하중과 진동에도 우수한 내구성을 발현한다.The packaging material composition of the present invention has a long pot life, so it is suitable for construction with a large construction target area such as a large road, and the curing time of the packaging material can be adjusted by heating the installed packaging material. In addition, the polyurethane binder composition has excellent strength as well as elongation, so that it exhibits excellent durability against continuously applied load and vibration.
또한, 포장재 조성물에 포함된 상기 폴리우레탄수지 코팅 나일론 중공사와 폴리우레탄수지 주쇄에 도입된 아크릴기는 폴리우레탄수지의 신율을 적절하게 제어해줌과 동시에 강도를 향상시켜 폴리우레탄수지가 온도 변화에 따라 수축율이 심하게 달라서 시공대상 도로 계면과 포장재 조성물간의 접착강도가 저하되는 것을 효과적으로 방지해 주고, 포장체의 소성 변화를 감소시켜주면서 포장체의 강도 및 마찰내구성을 향상시켜준다.In addition, the polyurethane resin-coated nylon hollow fiber included in the packaging material composition and the acrylic group introduced into the polyurethane resin main chain appropriately control the elongation of the polyurethane resin and at the same time improve the strength, so that the polyurethane resin shrinks according to the temperature change. It effectively prevents the deterioration of the adhesive strength between the road interface to be constructed and the pavement composition due to the severe difference, and improves the strength and friction durability of the pavement while reducing the plastic change of the pavement.
